目的了解卡介苗接种后儿童结核免疫状况,为改善卡介苗接种工作提供依据。方法应用结核菌素纯蛋白衍生物(PPD)试验,对514名儿童进行卡介苗接种3个月后阳性率调查。结果县疾控中心接种门诊,乡镇卫生院,外来流动儿童卡介苗接种阳性率分别为89.4%,60.82%,54.55%,不同年龄阳性率有显著的统计学意义,卡疤大小与阳性率成正比,男女比例阳性率差异无显著的统计学意义。结论加强接种人员的卡介苗接种技术培训和流动儿童管理,可提高接种质量。
Objective To understand the immunological status of tuberculosis in children after BCG vaccination, so as to provide basis for improving BCG vaccination. Methods The positive rate of 514 children after three months of BCG vaccination was investigated by using the tuberculin pure protein derivative (PPD) test. Results The positive rates of BCG vaccination in county CDC vaccination clinics, township hospitals and migrant children were 89.4%, 60.82% and 54.55%, respectively. The positive rates of different ages had significant statistical significance. The size of card scar was positively correlated with the positive rate, No significant difference was found in the positive rate of male to female ratio. Conclusion Strengthening vaccination BCG vaccination training and floating child management can improve vaccination quality.
